Project Description

This juvenile giant Pacific chiton (Cryptochiton stelleri) is recognizable by the bristles found on its dorsal surface.  Apparently most juveniles do not have such an abundance of bristle clusters, so this was a unique find.  This specimen was only about an inch (2.5 cm) long.  Adult giant Pacific chitons are the largest chitons in the world, reaching fourteen inches (35.5 cm) in length.  Its eight shell plates are fully enveloped by the girdle.
